Curved detector: omg!

      Comments Off on Curved detector: omg!

Recent picture taken with our customized fish-eye optical system (optimization: Wilfried Jahn) The system has a 178 degrees field of view. Vignetting is mostly suppressed except for the very edge of the image. The system works with a convex sensor, full frame, 20Mpixels, produced by the CEA-LETI. The full optical characterization is ongoing and will be published by the end… Read more »

Curved detectors: First images!

      Comments Off on Curved detectors: First images!

This picture, 135 degrees Field of view, was obtained out of a fish-eye like objective made of 9 lenses and 3 materials. Compared to the existing systems, we gain about one third of the optics and reduce the number of required materials of about 70%. The custom fish-eye objective made of 9 lenses, only spherical surfaces, and using the curved… Read more »

Curved detectors: first concave prototype delivered!

      Comments Off on Curved detectors: first concave prototype delivered!

Our brand new prototype of a concave curved detectors has been delivered at LAM this week! This full frame, fully-functional, 20Mpixels concave CMOS detector perfectly works in the visible. With a radius of 150mm over a size of 24x32mm², such a breakthrough device will allow to drastically reduce the amount of lenses required in wide field imaging systems, as well… Read more »

Thanks to Dennis Overbye, our work is cited in the Science section of the New York Times.The author describes how much of a breakthrough the DARPA sky surveillance telescope is, with its large curved and active focal plane. See the following link to the New York Times – Science blog.

51-Peg, a discovery triggered by Marseille’s instrumentation

      Comments Off on 51-Peg, a discovery triggered by Marseille’s instrumentation

Our research group in Marseille has quite an interesting legacy in the field of exoplanets. Interestingly, this part of the story is well known by the exoplanets community, as it has been presented by Stéphane Udry in his historical talk at the SOPHIE’s 10-years celebration. 51 Peg, the very first exoplanet discovered in 1995, has been detected with the ELODIE… Read more »
